The Soil: Texture And Structure
The term 'soil texture' describes the size and mix of a soil's constituent particles and determines much of its physical character.
Soil particles are classified according to the following sizes
- > 2 mm gravel
- 0.2-2 mm coarse sand
- 0.02 - 0.2 mm fine sand
- 0.002 - 0.02 mm silt
- < 0.002 mm clay
Textural classes can then be described according to the various mixtures of particles.
Many of the major classes are shown in the accompanying 'texture pyramid'.
